Membranes and separators from cellulose fibrils of different degrees of refining Open
Membranes and separators are crucial components in many processes and devices. The state-of-the-art fossil-based membranes have a high carbon footprint, and polyfluorinated membranes are increasingly phased out. These limitations lead to a…

Dynamic nuclear polarization solid-state NMR spectroscopy as a tool to rapidly determine degree of modification in dialcohol cellulose Open
Dialcohol cellulose can be prepared by periodate-mediated oxidation of cellulose followed by reduction with borohydride. The two-step reaction creates a modified cellulose polymer which is ring-opened between the C2 and C3 carbons in the g…

Predicting orientation in extruded wood polymer composites Open
A general procedure for combining material functions and numerical modeling to predict the orientation of highly filled wood polymer composites (WPCs) in a single screw extrusion and validation thereof is elaborated in this study. Capillar…

Dewatering of Micro- and Nanofibrillated Cellulose for Membrane Production Open
Cellulose-based membranes have tremendous potential to improve the sustainability and performance of high value applications, such as filters and energy devices, particularly as fluorinated compounds are becoming more regulated. Yet, a dee…

Mapping surface defects in highly-filled wood fiber polymer composite extrusion from inline spectral analysis Open
Surface defects in highly-filled wood polymer composites (WPCs) are mapped in single-screw extrusion via inline optical spectral analysis for the first time. The effects of wood fiber content and drying on the dynamics of surface defects a…

Highly Ductile Cellulose-Rich Papers Obtained by Ultrasonication-Assisted Incorporation of Low Molecular Weight Plasticizers Open
Fiber-based materials are attractive sustainable alternatives to fossil-based plastics, however, the lack of ductility (i.e., brittleness) limits their applicability in complex shapes as are often utilized for plastics. In this study, we h…

Surface instability detection in highly-filled biocomposites from inline imaging during extrusion Open
The processing of wood fiber biocomposites, and in particular, the extrusion, is accompanied by multiple challenges, among which agglomeration, entanglement, slip, or surface instabilities being the most common ones. In the current work, w…
